Pearl onions are often underused as a side dish, but their mild flavor pairs well with the earthy mushrooms and sweet fennel. The cornstarch adds a gravy-like sauciness to this dish from the rich juices, but for something a little creamier, add a few splashes of coconut milk at the end of cooking.
Pearl Onions, Mushrooms, and Fennel
2 tablespoons (15mL) extra virgin olive oil
1 pound (454g) frozen pearl onions, thawed and drained
1 small head fennel, thinly sliced
1/2 pound (227g) cremini mushrooms, thinly sliced
1 teaspoon (5mL) dried oregano
Fine sea or Himalayan salt to taste
3 tablespoons (45mL) water
1 teaspoon (5mL) cornstarch
Heat the oil in a large skillet over medium heat. Add the pearl onions and cook until they start to brown, stirring often, about 10 minutes. Add the fennel, mushrooms, and oregano. Cook until the mushrooms are softened, about 5 minutes more. Sprinkle with salt.
Mix the water with the cornstarch in a small bowl to create a slurry. Pour the cornstarch mixture over the pearl onion mixture. Mix well. Turn to low heat and cook for about 3 minutes, until the sauce has thickened. Season with additional salt to taste. Serve warm.
